Diatom responses to late Quaternary vegetation and climate change, and to deposition of two tephras in an alpine and a sub-alpine lake in Yoho National Park, British Columbia
The late Quaternary diatom records from alpine Opabin Lake (altitude 2285 m a.s.l.) and sub-alpine Mary Lake (altitude 2054 m a.s.l.), located in Yoho National Park, British Columbia (lat. 51 ° 21′N;Expand
The developmental history of peatlands at Muskiki and Marguerite lakes, Alberta
The peat stratigraphy of fens at Muskiki Lake (52°50′N, 116°51′W) and Marguerite Lake (54°38′N, 110°43′W) in central Alberta was examined to determine the developmental history of the fens on theExpand
Holocene paleohydrology of central Alberta: testing the general-circulation-model climate simulations
Paleoecological investigations of 28 lakes and bogs provide the basis for a Holocene paleohydrological record for central Alberta. Shallow basins, empty during the early Holocene, began floodingExpand
Late Quaternary environmental change in the Lake O'Hara region, Yoho National Park, British Columbia
Abstract Palaeoenvironmental reconstructions for the upper Cataract Brook Valley are derived from radiocarbon and tephra dated cores recovered from subalpine Lake O'Hara and alpine Opabin LakeExpand
The Late Quaternary palaeoenvironmental history of a presently deep freshwater lake in east-central Alberta, Canada and palaeoclimate implications
Abstract The palaeoenvironmental history of Moore Lake, Alberta, Canada (54°30′N; 110°30′W) has been investigated through analysis of pollen, diatoms, total chrysophyte stomatocysts, and sedimentaryExpand
Baptiste Lake, Alberta — A late Holocene history of changes in a lake and its catchment in the southern Boreal forest
Palaeoenvioonmental investigations based upon sediment cores retrieved from Baptiste Lake, Alberta (longitude 114° 34′ W; latitude 54° 45′ N) show that the sedimentary record spans approximately 4600Expand
The Standing Crop and Primary Productivity of the Phytoplankton of Abbot's Pond, North Somerset
The investigations of Moss (1967a, 1969a, b, c), Happey (1968, 1970a, b, c, d) and Hickman (1970) showed that, owing to its location in a sheltered tree-lined valley, Abbot's Pond, north Somerset,Expand
LONG-TERM TILLAGE AND CROP ROTATION EFFECTS ON SOIL CHEMICAL AND MINERAL PROPERTIES
ABSTRACT Soil samples from archives and newly collected groups were analyzed to examine changes in mineral nutrient availability and selected soil chemical factors under long-term management systems.Expand
History of a presently slightly acidic lake in northeastern Alberta,Canada as determined through analysis of the diatom record
The Holocene sedimentary diatom record from Otasan Lake, Alberta, has been analyzed to determine the development of this presently slightly acidic lake. The changes in the lake have been linked toExpand
Starch-Encapsulated Atrazine: Efficacy and Transport
Current data indicate that pesticides are a contributor to the groundwater contamination problem, with the herbicide atrazine [6-chloro-N-ethyl-N'-(1-methylethyl)-1,3,5-triazine-2,4-diamine] one ofExpand
